[0045] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0046] Please refer to Figure 1 and Figure 2, the photoelectric switch structure provided by the embodiment of the present invention is now described. The photoelectric switch structure includes a first mounting seat 1, a moving assembly 2, a second mounting seat 3, a photoelectric sensor 4 and a light shielding assembly 5. Among them, the moving assembly 2 is slidably connected to the first mounting seat 1 along the first direction L1, the second mounting seat 3 is arranged on one side of the first mounting seat 1, the photoelectric sensor 4 is fixed on the second mounting seat 3, and the light shielding assembly 5 is movably connected to the second mounting seat 3 along the second direction L2 perpendicular to the first direction L1, and is transmission-connected to the moving assembly 2, and is used to extend into the photoelectric sensor 4 under the drive of the moving assembly 2 to block the propagation of light. The moving assembly 2 slides along the first direction L1 to drive the light shielding assembly 5 to move along the second direction L2, thereby shielding the photoelectric sensor 4.

[0047] Compared with the prior art, the photoelectric switch structure provided by the present invention fixes the photoelectric sensor 4 on the second mounting base 3 and movably connects the shading component 5 to the second mounting base 3 along the second direction L2. When the movable component 2 moves along the first direction L1, it pushes the shading component 5 to move along the second direction L2, so that the shading component 5 extends into the photoelectric sensor 4 to block the propagation of light, that is, the displacement in the first direction L1 can be converted into the displacement in the second direction L2, so that the installation direction of the photoelectric sensor 4 is no longer limited to the direction parallel to the moving direction of the movable component 2, thereby solving the technical problem that the overall structure of the existing photoelectric switch structure is not compact and affects the placement of other components.

[0048] It should be noted that the first direction L1 is a horizontal direction, and the second direction L2 is a vertical direction perpendicular to the horizontal direction. Of course, the second direction L2 can be other directions, which is not limited here.

[0049] In another embodiment of the present invention, see further Figures 1 to 3 The moving assembly 2 includes a moving member 21 and a wedge block 22. The moving member 21 is slidably connected to the first mounting seat 1 along the first direction L1, and the wedge block 22 is fixed on the side of the moving member 21 facing the second mounting seat 3. The wedge block 22 is used to drive the shading assembly 5 to move along the second direction L2 to extend into the photoelectric sensor 4, and the end surface of the wedge block 22 that contacts the shading assembly 5 is inclined.

[0050] Specifically, the moving member 21 is an electrode copper sheet, a slide groove is provided on the first mounting seat 1, and the moving member 21 is installed in the slide groove. The first mounting seat 1 is an insulating member, which is used to stabilize the moving direction of the moving member 21. The moving member 21 is a block structure, and the wedge block 22 is a rectangular block structure. The moving member 21 and the wedge block 22 are connected by a second connecting plate 23, and the second connecting plate 23 is a bent plate. One end of the second connecting plate 23 is connected to the moving member 21 by a fastener such as a screw, and the other end of the second connecting plate 23 is connected to the wedge block 22 by a fastener such as a screw. Since the end face of the wedge block 22 in contact with the shading component 5 is inclined, when the wedge block 22 moves, it will drive the shading component 5 to move in the second direction L2.

[0051] Of course, in other embodiments, the wedge block 22 and the shading assembly 5 can be driven by a worm gear to convert the horizontal motion into vertical motion, which can be selected according to specific needs.

[0052] In another embodiment of the present invention, see Figures 1 to 3 In order to assist the moving member 21 in resetting, the photoelectric switch structure further includes a first resetting member 6, the two ends of which are respectively connected to the moving member 21 and the second mounting seat 3. When the moving member 21 moves, it will squeeze the first resetting member 6, and the first resetting member 6 will generate an opposite force. When the moving member 21 is separated from the driving of the power source, the elastic force of the first resetting member 6 will drive the moving member 21 to move in the opposite direction, thereby assisting the moving member 21 in resetting.

[0053] Specifically, in the present embodiment, the first reset member 6 is a spring, and the two ends of the spring are respectively connected to the moving member 21 and the second mounting seat 3. Of course, in other embodiments, the first reset member 6 is a spring, and the two ends of the spring are respectively connected to the moving member 21 and the second mounting seat 3.

[0054] Specifically, in this embodiment, further combined with Figure 9 The second mounting seat 3 includes a connecting portion 31 and a limiting portion 32. The connecting portion 31 is connected to the first mounting seat 1, and the limiting portion 32 extends from one side of the connecting portion 31 in a direction away from the connecting portion 31. The limiting portion 32 is used to abut against the moving member 21 to limit the moving distance of the moving member 21. The two ends of the first reset member 6 are respectively connected to the moving member 21 and the limiting portion 32.

[0055] In another embodiment of the present invention, refer to Figure 1 , Figure 4 and Figure 5, the shading assembly 5 includes a shading member 52 and a second resetting member 53. The end surface of the shading member 52 in contact with the wedge block 22 is an inclined surface or an arc surface. By setting the end surface of the shading member 52 in contact with the wedge block 22 as an inclined surface or an arc surface, the movement in the first direction L1 can be converted into a displacement in any direction, and it is only necessary to change the direction of the inclined surface of the wedge block 22. The two ends of the second resetting member 53 are used to abut against the shading member 52 and the second mounting seat 3 respectively, so that the shading member 52 keeps a tendency to move away from the photoelectric sensor 4.

[0056] Preferably, the end surface of the shading member 52 that contacts the wedge block 22 is a spherical surface.

[0057] Furthermore, in the present embodiment, the shading assembly 5 also includes a mounting shell 51, which is fixed on the second mounting seat 3, and the shading member 52 is passed through the mounting shell 51. The interior of the mounting shell 51 is hollow to form a receiving space, and the second reset member 53 is arranged in the receiving space, and the two ends of the second reset member 53 are respectively abutted against the shading member 52 and the mounting shell 51.

[0058] When the wedge block 22 in the moving assembly 2 squeezes the shading member 52, the shading member 52 will drive the second restoring member 53 to move. Since one end of the second restoring member 53 abuts against the mounting shell 51, the second restoring member 53 is compressed. The compression of the second restoring member 53 will generate an upward force. When the shading member 52 is out of contact with the wedge block 22, the shading member 52 will be reset under the action of the second restoring member 53.

[0059] Specifically, in this embodiment, the second reset member 53 is a spring, and the two ends of the spring are respectively in contact with the end of the shading member 52 away from the photoelectric sensor 4 and the mounting shell 51. Of course, in other embodiments, the second reset member 53 is a spring, and the two ends of the spring are respectively in contact with the end of the shading member 52 away from the photoelectric sensor 4 and the mounting shell 51, which can be selected according to specific needs. The mounting shell 51 is a shell structure, and the mounting shell 51 includes a bottom shell portion 511 and a cover portion 512 that are butt-jointed with each other, and the bottom shell portion 511 and the cover portion 512 are connected to form a storage space for accommodating the second reset member 53.

[0060] Furthermore, the shading assembly 5 further includes a spring clip 54, which is fixed to the shading member 52 and is located between the mounting shell 51 and the second reset member 53, that is, one end of the second reset member 53 abuts against the spring clip 54. Specifically, a slot 5211 is provided on the shading member 52, and the spring clip 54 is clamped on the slot 5211, so that one end of the second reset member 53 abuts against the spring clip 54, and under the action of the second reset member 53, the shading member 52 is reset.

[0061] Specifically, in this embodiment, the light-shielding member 52 includes a rod portion 521 and a light-shielding portion 522. The rod portion 521 is used to contact the moving component 2. The second reset member 53 is sleeved on the rod portion 521. The light-shielding portion 522 extends from one end of the rod portion 521 toward the direction of the photoelectric sensor 4, and the mounting shell 51 abuts against the light-shielding portion 522. Specifically, the rod portion 521 is a cylindrical rod-shaped structure, the light-shielding portion 522 is a cuboid structure, and a card slot 5211 is formed on the rod portion 521.

[0062] In another embodiment of the present invention, further referring to Figure 8 , a groove 40 is formed on one side of the photoelectric sensor 4. One side of the groove 40 facing the light-shielding assembly 5 has an opening 401. The light-shielding assembly 5 is inserted into the groove 40 through the opening 401. Transmitting tubes (not shown in the figure) and receiving tubes (not shown in the figure) are respectively provided on opposite side walls of the groove 40. Specifically, both the transmitting tube and the receiving tube are an infrared transmitting tube and an infrared receiving tube. The infrared rays emitted by the infrared transmitting tube are received by the receiving tube. The light-shielding member 52 is inserted into the groove 40, so that light can be blocked.

[0063] In another embodiment of the present invention, referring to Figure 2 , Figure 5 , Figure 6 and Figure 7 , the photoelectric switch structure further includes a first connecting plate 7. One end of the first connecting plate 7 is connected to the second mounting seat 3, and the other end of the first connecting plate 7 is connected to the light-shielding assembly 5 and the photoelectric sensor 4. Specifically, the first connecting plate 7 is a bent plate. One end of the first connecting plate 7 is connected to the second mounting seat 3 through fasteners such as screws, and the other end of the first connecting plate 7 is connected to the light-shielding assembly 5 and the photoelectric sensor 4 through fasteners such as screws. The light-shielding assembly 5 further includes a third connecting plate 55. The third connecting plate 55 is a bent plate, and the third connecting plate 55 is connected between the mounting shell 51 and the first connecting plate 7.

[0064] It should be noted that in this embodiment, the number of the light-shielding assemblies 5 is two. Correspondingly, the number of the photoelectric sensors 4 is two. The number of the wedge-shaped blocks 22 can be two, which are respectively connected to both ends of the moving member 21. When the moving member 21 moves, it drives the two wedge-shaped blocks 22 to move simultaneously, and then drives the two light-shielding assemblies 5 to move simultaneously, in order to prevent electric shock accidents or the product from malfunctioning in case one of the groups fails.

[0065] Please refer to Figures 1 to 3 , the present invention further provides an electronic device, and the electronic device includes the photoelectric switch structure in any of the above embodiments.

[0066] For the electronic device provided by the present invention, the above-mentioned photoelectric switch structure is adopted, so that the overall structure is relatively compact.

[0067] Furthermore, the electronic device further includes a control module (not shown in the figure) communicatively connected to the optoelectronic sensor 4. When the moving component 2 pushes the light-shielding component 5 such that the light-shielding component 5 is located between the grooves 40 of the optoelectronic sensor 4, the infrared rays emitted by the transmitting tube will be blocked by the light-shielding component 5. Then, the receiving tube cannot receive light and the signal is interrupted, and the control module controls the electronic device to turn on the circuit. On the contrary, when the moving component 2 is reset under the action of the first reset member 6, the light-shielding member 52 of the light-shielding component 5 will be reset under the action of the second reset member 53, so that the light-shielding component 5 leaves the grooves 40 of the optoelectronic sensor 4. The infrared rays emitted by the transmitting tube will be received by the receiving tube, and the control module controls the electronic device to turn off the circuit, thereby realizing the intelligent power-on and power-off function of the electronic device and avoiding the occurrence of electric shock accidents.

[0068] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
